Y BICYCLE ALARM-WHISTLE.

SPECIFICATION forming part 0f Patent; N0. 689,202, dated December 17, 1901.

Application iiled April 13, 1901. SerialrNo. 55.695. (No mode1.\

To all whom/'it rrul/yconcern:

Beit known that I, LOUIS L. LA MERE, a citizen of the United States, residing at Mosinee, in thecounty of Marathon and State of Wisconsin, have invented a new and useful Bicycle Alarm-Whistle, of which the follow-` Vor set to cause a louder or softer tone; and

with these objects in view my invention consists in certain new and useful combinations of parts, as will be fully described in the following specifcationand pointed out in the claims, reference being had to the accompanying drawings, in whichi Figure l represents the front portion of a bicycle with my invention applied. Fig. 2 is a detail section taken about on the 1ine2 2 of Fig. 3. Fig. 3` is a cross-section on the line 33 of Fig. 2. Fig.l 4 is a plan view with one member of the fork to which my invention is connectedv shown in section and with parts of the casing also shown in section, and Figs. 5 and 6 are detail views of the construction.

In the drawings, A indicates a bracket that is firmly clamped to one arm of the front fork of 'a bicycle and having its outer end provided with dowinwardly-projecting arms a, which pass through perforated lugs b and b', formed on the side of the fan-casing B. Spiral springs C are arranged uponthe arms @,which bear at their upper ends against collars a', held on the arms, and at their lower vends against the lugs b, the purpose of which is to normally hold the casing down, as will more fully appear later on.

Thecasing B is preferably made circular in shape, having one portion of its periphery terminating in an open mouth section b2, that is arranged across the mouth of the whistletube C'. This tube is secured upon the peripheral surface of the casing and has one side thereof provided with a slot through which passes the shank of a thu nib-screw D, which holds acylindrical plug E, that snugly fits within the tube to any position desired. The purpose of this plug is to change the tone of the whistle, as it will be readily understood that yby moving the plug in either direction 'the tone of the whistle may be changed accordingly. In practice I prefer to make the plug hollow, which lessens. the weight, and to make the body somewhat elongated, so that it will cover the slotin the casing no 'matter to what position it may be placed. It will of course be' understood that tube to permit of the adjustment just described.

A shaft F is journaled within the casing, upon which is loosely mounted the hubg of a fan G, havingone end formed with a pinion g', that protrudes through an opening formed in one sideof the casing and is engaged by a gear-wheel H, journaled on a short shaft h upon the side of the casing, as shown. The outer end of the shaft h isl journaled in a bracket I, formed on the side of the casing, which also supports one end of the shaft F.

' Formed integral with the gear I-I is a pinion h', which is engaged by a gear-wheel J,

carriesat its outer end a frictional wheel K, that is arranged for engagement with the rim of the front wheel of a bicycle. The normal position of this wheel is down or out of engagement with the wheel of the bicycle, and in order to bring them into engagement I connect to the top of the casing a cord or chain L, that extends up to the handle-bar within easy reach of the rider.

One side of the casingV is provided with openings b3, through which air is admitted when the fan is in motion. A plate M is pivoted to the casing for closing the journal of the shaft and is provided with an aperture through which `oil is fed to the bearings.

i The application and operation of my invention are as follows: -The casing is first positoned upon the arms of the bracket and the latter secured to the fork of a bicycle in such position thatthe frictional wheel is clear of the rim of the bicycle and the cord is connected to the casing and handle. Now when the wheel is in motion and the rider desires the plug is to have the same radius as theA that is keyed upon the shaft F; which latter Y to give an alarm he draws upon the cord,

f which raises the casingagainst the `tension ot' the springs and brings thefrctional wheely into contact with the` rim of the bicycle#y wheel, which causes the-fritional wheel to revolve and through the .gears imparts a rapid motion tothe fan, which forces air through the mouth of the casing across the `top of the tube and produces a whistling sound. f t

By my invention -it will be seen that I providea simple inexpensive alarm that can'he easily applied to a bicycle and one that will produce a sound that will ofthe rider; y

It will of course be understood that when ythe tension ol the cord is released the spring i ond shaft journaledon the outside of the cas` ing, a pinion formed integral with the gearwheel, and adapted for engagement with a gear-wheel fixedly held upon ,the fan-shaft, and means carried by the said fan-shaft for can hechanged at the imparting motion to the fan through Hthe mei dium ofthe gear wheels and pinion's, sub- 35 stantially as shownv and described.

2. In a bicycle-alarm, the combination ot'a l fan-casing having a tube arranged integrally` on the periphery thereofand having a slot arranged therein, a plug adapted to operate within the tube and having a threaded aperture arranged therein, a thumb-screw pro-4 jecting through the said slot andadapted to engage the` said threaded aperture whereby f,

the said plug may be held to any adjusted position, a fan adapted to operate within the casing, and means for operating the fan substantially as shown and described.

` 3. In a bicycle-alarm thecombination of a faufcasing having a tube arrangedon the periphery thereof, a shaft journaled withinl the casing, a wheel fxedly held on the said shaft,

a fan loosely held on the shaft within the 'l casing and having a portion of its hub provided with a pinion, which is adapted for engagement with a gearjournaled kuponthe side of the casing and having a pinion formed therewith that is adapted forengagement with a gear-wheel ixedly held on the shaft upon which the fan is held, and means for revolving the shaft for the purpose shown and de-v scribed.
